I have a simple question, is there a very fast and effecient way to generate
random numbers that are fast on the fly. The numbers are really randomize
and distorted...

 * generates a random number between a and b *
 * @param a the starting range *
 * @param b the integer ending range *
 * @return N such that a <= N <= b *
template <class T>
T randint(const T& a, const T& b)
  assert (b >= a);
  typedef boost::minstd_rand base_generator_type;
  typedef boost::uniform_int<> distribution_type;
  typedef boost::variate_generator<base_generator_type&, distribution_type>
  base_generator_type generator(boost::numeric_cast<unsigned
  gen_type ran_gen(generator, distribution_type(a, b));
  for (int i = 0; i < 30000; ++i)
      generator.seed(boost::numeric_cast<unsigned long>(clock()));
  return ran_gen();

This works but is super slow... are there effective ways to do it...
